Three kinds of fortified biscuits and bread were given as breakfast for 5 months to 106 preschool children 4-6 years old lodged in a kindergarten, with a control group taking common biscuits and bread without fortification. 6 g protein and 160 kcal were supplied by 50 g of fortifed foods in which 0.25 g lysine, 0.25 g lysine and 0.8 mg riboflavin, and cod liver oil and calcium in addition to lysine and riboflavin were fortified respectively. The results showed that a diet with intake of 2.1 g protein and 71 kcal/kg body weight fortified on the average by 228 mg lysine or 228 mg lysine and 1.1 mg riboflavin increased the monthly increment of body weights, heights, and urinary excretions of creatinine per day. There was also a tendency of improvement, in nitrogen retention. The urinary excretion of riboflavin in load test was increased in the group taking the second kind of fortified foods.

Objective To observe the value of multimodal imaging for diagnosis of cardiac space-occupying lesions.Methods Data of 70 patients with cardiac space-occupying lesions who underwent echocardiography and cardiac CT(CCT)were retrospectively analyzed,among them 35 also underwent cardiac MRI(CMRI).The value of multimodal imaging for diagnosis of cardiac space-occupying lesions were explored according to the results of surgical pathology or clinical diagnosis.Results Among 70 cases,benign tumors were confirmed by surgical pathology in 43 cases,while malignant tumors were confirmed by surgical pathology in 3 cases and clinically diagnosed in 1 case.Meanwhile,non-tumor-occupying lesions were clinically diagnosed in 23 cases,all obviously shrunken after treatments.Among 70 cases,echocardiography correctly diagnosed 57 cases,misdiagnosed 8 cases and unclearly diagnosed 5 cases,with diagnostic accuracy rate of 81.43%(57/70).CCT correctly diagnosed 63 cases,misdiagnosed 4 cases but missed 3 cases,with diagnostic accuracy rate of 90.00%(63/70).CMRI outcomes in all 35 cases were consistent with surgical pathologic results,with diagnostic accuracy rate of 100%(35/35).Conclusion Multimodal imaging might provide objective evidences for diagnosis and treatment of cardiac space-occupying lesions.

Objective:To investigate correlation between neutrophil lymphocyte ratio(NLR),IL-6 and lymphocyte subsets and prognosis of viral pneumonia complicated with acute respiratory distress syndrome(ARDS).Methods:A total of 98 patients with viral pneumonia complicated with ARDS admitted to Xinxiang Central Hospital/the Fourth Clinical College from May 2017 to June 2019 were selected,NLR,IL-6 and lymphocyte subsets expressions in patients with different severity were analyzed.Correlation between NLR,IL-6 and lymphocyte subsets levels in prognosis of viral pneumonia complicated with ARDS was analyzed by Pearson correlation.Logistc regression was used to analyze prognostic risk factors of viral pneumonia complicated with ARDS.Results:With aggravation of viral pneumonia complicated with ARDS,NLR and IL-6 levels were significantly increased(P<0.05),while CD3+T,CD4+T and CD19+T cells levels were significantly decreased(P<0.05).Pearson correlation analysis results showed that NLR and IL-6 were positively correlated with prognosis of viral pneumonia complicated with ARDS(P<0.05),while CD3+T,CD4+T,CD19+T and CD8+T cells were negatively correlated with prognosis of ARDS with viral pneumonia(P<0.05).Multivariate Logistic analysis showed that NLR,IL-6,CD3+T and CD19+T cells were risk factors for viral pneumonia complicated with ARDS(P<0.05).Conclusion:Serum NLR,IL-6,CD3+T and CD19+T cells are closely related to severity and prognosis of patients with viral pneumonia complicated with ARDS.
